Tuesday is AD&D night around here, so I'm spending some time before the game to get all my campaign ducks in a row, so to speak. One thing that's topping my list at the moment is an overland map - I don't have one (or at least one with a finer scale than the Darlene map's 30 mile hex - great for getting an overview, but not so useful for hexcrawl-style wilderness adventure). So far we've been concentrating on the dungeon (Castle Greyhawk), with the city itself (Free City of Greyhawk) only just starting to show up in play - but it's only a matter of time before somebody picks up one of the adventure hooks laying around (or gets bored) and wants to do some hiking.
Bat in the Attic blog (a fine OSR destination if you haven't checked it out yet) outlines 34 steps to make a fantasy sandbox, and I'm dying to try his method. The first three steps (1 world map, 2 label important regions, 3 write region blurbs) are already taken care of thanks to the World of Greyhawk folio, and step 4 is to choose your starting region - again, centering on the Free City of Greyhawk, the choice is made for me. Steps 5-10 involve detailing the local map, so that's where I'll be starting.
Now, surprisingly, there's not a single zoomed-in hexmap of the Greyhawk region that I can find. There are plenty of beautifully illustrated maps out there, most of which look like they'd be useless in my gaming (and most of which incorporate elements from 2e modules and the 3e Living Greyhawk campaign, none of which I'm using). So it falls to me to create a usable hexcrawl map of the area. I'll likely be doing this with the DMG random terrain tables as inspiration (although I'll place the result generated with some mind as to "realistic" terrain).
Something else I stumbled across last night: Bat in the Attic has also put up a great rundown-by-pantheon of the Greyhawk deities - something I've meant to do for quite some time (long enough that I probably never would have). The posting is HERE, and the full rundown is HERE. Great stuff.
